August 1, 2025 · 1 sources

Boss released PX-1 system program Ver.1.10 in August 2025, according to the update history on the PX-1 updates and drivers page¹. The entry for Ver.1.10 lists "Support for BOSS EFFECT LOADER" under additional functions and "Fixed other minor bugs" under bug fixes¹.

The page does not describe what Effect Loader does or how it works with the PX-1. The only other detail given for Ver.1.10 is the minor bug fixes¹.

The same page lists a later release, Ver.1.11, dated February 2026, whose bug fixes include "Fixed system vulnerabilities" and "Fixed other minor bugs"¹. The update instructions on the page cover Ver.1.11: users check the app version in the VERSION section of the MENU screen, and if it shows "APP: 1.11," there is no need to update¹. The update requires the PX-1, a USB Type-C cable and a Windows or Mac computer with a USB 2.0 or USB 3.0 port¹. Boss warns that the update data must never be applied to any product other than the PX-1, that the included adapter should be used, and that the power must not be switched off during the update¹. If a power failure or similar accident occurs mid-update, the PX-1 will not start up in normal operating mode and will require servicing through a Roland service center¹.
